Denon Perl Pro True Wireless Earbuds

Verdict

Top-tier sound and deep personalization with excellent aptX codec support, but the bulky fit, mixed transparency/ANC, and occasional app/firmware dependency make it best for audiophiles who will tinker rather than convenience-first buyers.

Pros

  • USB-C ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 5.0
    USB-C charging is standard and consistently present, often paired with Qi wireless charging. No major complaints are raised about the USB-C implementation.
  • Audio-video sync accuracy ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.8
    Latency is reported as well controlled in at least one video test, with no noticeable audio-video sync issues. Broader cross-review evidence is limited, but nothing flags major lip-sync problems.
  • Ear tip size options ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 10 reviews 4.7
    There are multiple ear tip sizes and materials plus wing supports, enabling a wide range of fit attempts. Some boxes include only a single foam pair, and fit success still varies by ear shape.
  • aptX ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 11 reviews 4.7
    aptX support (including Adaptive and Lossless) is repeatedly called out as a standout advantage for high-quality Bluetooth audio. However, Snapdragon Sound requirements mean not all Android phones can use the best modes.
  • Included accessories ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.6
    Included accessories are generous, typically providing multiple silicone tip sizes, at least one foam option, and wing supports plus a charging cable. This helps users dial in fit and seal, though foam quantity may be limited.
  • Maximum volume clarity ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.6
    Clarity remains high at louder levels with low perceived distortion in multiple reviews, supporting confident listening at higher volumes. If tuning is not updated or personalized well, the tonal balance may still sound wrong even when clean.
  • Codec support ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 11 reviews 4.6
    Codec support is a major selling point, including AAC/SBC plus aptX Adaptive and aptX Lossless on compatible sources. Real-world benefit depends on your phone or computer support, with some devices falling back to AAC.
  • Instrument separation ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.6
    Instrument separation and imaging are strong, with clean layering that keeps complex mixes from turning muddy. A few critiques focus more on rhythmic cohesion and dynamics than on separation itself.
  • Sound quality ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 11 reviews 4.6
    Sound quality is frequently described as pristine, spacious, and among the best in true wireless—especially after running Masimo AAT personalization and/or updating firmware. A minority of testing notes that stock or older firmware tuning can sound off and may require EQ tinkering to reach its potential.
  • Soundstage width ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 9 reviews 4.5
    Soundstage is widely reported as wide, open, and airy for earbuds, contributing to a speaker-like sense of space. Depth can feel a bit flat to some, and personalization/spatial processing can change the perceived openness.
  • Volume output ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.5
    Volume output is typically high with plenty of headroom, and several reviewers call them louder than many competitors. Social/transparency modes may cap volume for situational awareness.
  • Sensors ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.5
    In-ear sensors support auto play/pause and can be configured in the app. Reviews that mention them report reliable behavior and useful customization.
  • Bass performance ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 10 reviews 4.5
    Bass is generally impactful and well controlled, with an immersion slider to add or trim low-end without heavy bleed. Some listeners still find the default/early tuning a bit lean or lacking ultimate bass power on demanding tracks.
  • Bluetooth connectivity stability ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.5
    Bluetooth stability is usually strong with fast reconnection and few dropouts, though isolated reports mention channel stutter in specific scenarios. Overall connectivity is viewed as a strength.
  • Midrange clarity ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.5
    Midrange is typically clear and well layered with strong vocal presence; several reviews note tasteful warmth and separation. Personal profiles can push mids forward or alter balance, so results vary by ear scan and EQ choices.
  • Multipoint connectivity reliability ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.5
    Multipoint is frequently highlighted as reliable, enabling convenient switching between two devices and handling calls vs media smoothly. It is considered a competitive feature at the premium tier.
  • Charging ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.4
    Charging is strong, with USB-C and Qi wireless support plus fast-charge behavior (about an hour of playback from a short charge). Case and bud recharge times are generally convenient for daily use.
  • Touch control responsiveness ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 10 reviews 4.4
    Touch controls are generally responsive with a large contact area and helpful feedback tones, and customization is a major plus. Some functions (like ANC toggling in certain workflows) may still rely on the app.
  • Equalizer customization ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.3
    EQ tools (including ProEQ and an immersion bass slider) provide meaningful tuning flexibility and can correct overly bassy or bright profiles. Users who like to fine-tune generally find the options robust.
  • Microphone quality for calls ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.3
    Call performance is commonly rated above average with clear speech, helped by multiple mics and aptX Voice support. Some reviewers still hear a slightly processed character compared with the very best earbuds for calls.
  • Build quality ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.3
    Build quality is generally praised as flagship-level, with solid construction and durable-feeling hinges and retention. Handling can be slightly awkward due to the earbuds’ size rather than materials quality.
  • Treble clarity ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.3
    Treble usually has detail and sparkle without harshness, but certain profiles or early firmware can yield peaky or tinny highs. EQ and firmware updates are commonly recommended if the top end sounds unnatural.
  • App ★ ★ ★ ★ ★ ★ ★ ★ ★ 10 reviews 4.2
    The Denon Headphones app is central for personalization, EQ, firmware updates, and control mapping, and is often praised for depth of features. A few users report stability issues such as crashes, so experience can vary by device/version.
  • Android compatibility ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.1
    Android support is strong, and Snapdragon-based phones can unlock aptX Lossless, but many popular Android devices cannot access the highest-bitrate Snapdragon Sound modes. Even so, several reviews note they still sound very good on non-compatible phones.
  • Stability ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.1
    Stability can be excellent when the right wings and tips are used, making them suitable for commuting and even cycling. However, some reviewers still experienced loosening or popping out over time, so fit testing matters.
  • Preset EQ profile quality ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.1
    Masimo AAT personalization profiles can dramatically reshape the sound and are frequently described as the defining feature. Results can be hit-or-miss depending on ear scan, tip seal, and preferences, so re-running the test or adding EQ may be needed.
  • Battery ★ ★ ★ ★ ★ ★ ★ ★ ★ 10 reviews 4.1
    Battery life is typically described as respectable with an advertised ~8 hours per charge, but at least one standardized test measured closer to ~6 hours with ANC use. Fast top-ups and the case make day-to-day use manageable.
  • Water/sweat resistance rating ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 4.0
    IPX4 water/sweat resistance is consistently noted, making them suitable for sweat and light rain. They are not intended for heavy water exposure or submersion.
  • Carry case quality ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.0
    The case is generally sturdy with good retention and wireless charging support, but its bulk and the earbuds’ sometimes-fiddly removal are common complaints. The case is also noted as not waterproof.
  • Noise isolation (passive) ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.0
    Passive isolation depends heavily on fit, but the nozzle shape, wings, and fit test help achieve a strong seal. With the right tips, physical attenuation is reported as meaningful even before ANC is applied.
  • Voice assistant integration ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.0
    Voice assistant actions can be assigned within the customizable control scheme, allowing quick access from taps. Reviews mainly note availability rather than deep assistant performance comparisons.
  • Spatial audio ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.0
    Spatial audio impressions vary widely: some reviewers find it immersive and bubble-like, while others call it subtle or not worth using. It is also noted as not head-tracked in at least one review.
  • Microphone noise reduction ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 3.9
    Noise reduction for calls is decent and wind handling is better than average, though wind and processing artifacts can remain audible. It generally keeps speech forward while pushing background sounds back.
  • Portability/foldability ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 3.8
    Portability is decent but not class-leading: the case fits in pockets yet is repeatedly called bulky, and the earbuds themselves are large. If you prioritize compact carry, smaller competitors may suit better.
  • Active noise cancellation effectiveness ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 3.8
    ANC is generally effective for commuting and office use, but it is not consistently class-leading versus top Bose/Sony/Apple options and can feel inconsistent. Still, many users report it forms a solid noise-reducing bubble when fit is good.
  • Multi-platform compatibility ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.8
    They work across phones and computers, but audio quality and feature access vary by platform and codec (aptX on Snapdragon vs AAC on iOS or some PCs). Expect the best performance on compatible Android hardware.
  • Design and Aesthetics ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 3.6
    Design is distinctive and polarizing: some like the elegant disc-like look and premium touches, while others find it awkwardly large and less luxurious than rivals. Color options appear limited in several regions.
  • Software/setup simplicity ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 3.6
    Setup is usually straightforward, but the app is effectively required for full functionality and can involve some tinkering to get ideal sound. Occasional app crashes or firmware dependency are the main simplicity drawbacks.
  • Comfort during long use ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 3.5
    Comfort is highly fit-dependent: some reviewers find them secure and comfortable with the right tips and wings, while others report pressure, heat, or discomfort during long sessions. The large shells are the main risk factor for smaller ears.

Cons

  • Transparency mode quality ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 3.3
    Transparency or social mode is divisive: some describe it as gentle and natural-sounding, while others report it is basic, less effective, or introduces artifacts and channel imbalance. Overall it trails the very best ambient implementations.
  • Weight comfort ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 3.2
    The earbuds are heavier and bulkier than many rivals, which can make them feel wearying over time for some users. Proper wings and tip selection can help distribute pressure but won’t eliminate size sensitivity.
  • Frequency response accuracy ★ ★ ★ ★ ★ ★ ★ ★ 1 review 2.8
    Frequency response accuracy is mixed: measurements and subjective notes suggest the out-of-box or early firmware tuning can be uneven. Firmware updates plus EQ/personalization generally bring the response closer to a balanced, pleasing curve.
  • Noise cancellation adjustability ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 2.7
    ANC control is somewhat limited: multiple reviews note it is largely on/off with adaptive behavior, with little or no manual intensity tuning. This can be frustrating for users who want finer control.
  • LDAC ★ ★ ★ ★ ★ ★ 1 review 1.0
    LDAC is not supported, which may matter to Android users who prefer Sony’s LDAC ecosystem. Buyers specifically seeking LDAC should consider alternative earbuds.
